Current Statistics
To refresh the list at any time, click Refresh
- Total received since started
- Total number of packets received by the executor since it started.
- Sent to nonforwarding address
- Total number of packets sent to the nonforwarding address since the executor started.
- Processed locally on this machine
- Total number of packets, not for the nonforwarding address or any cluster, but to be
processed locally by the Dispatcher machine.
- Sent to collocated server
- Total number of packets explicitly forwarded to a server collocated on the Dispatcher
machine.
- Forwarded to any cluster
- Total number of packets forwarded to any cluster.
- Not addressed to active cluster/port
- Total number of packets not addressed to any active cluster and port.
- KBytes transferred per second
- The number of kilobytes transferred over a one-second interval.
- Connections per second
- The current number of connections per second.
- Headers too short
- Total number of packets discarded by the executor because the packet headers are too
short.
- No port or servers
- Total number of packets that were forwarded to a cluster, but were discarded by the executor
because either the port:
- Did not exist
- Existed but had no servers configured to it
- Network adapter failure
- Total number of packets not forwarded because of a network adapter failure.
- Forwarding errors
- Total number of packets with forwarding errors since the executor started.
Examples of forwarding errors are:
- There was an error extracting an encapsulated packet that came in from a wide area
Load Balancer
- An attempt to forward the packet to either a local or remote server failed
Configuration Settings
Edit any of the values on the Configuration Settings tab, then click
Update Configuration.
- Nonforwarding address
- The address of this machine in either dotted-decimal or host name format. Any packet
sent to this address will not be forwarded by the Dispatcher component.
- Client gateway address
- The address of the network router through which traffic returns to the
client. This applies only to port forwarding method values of NAT/NAPT and content-based
routing. Type the address of the client gateway in either dotted-decimal or host name format.
- FIN count
- The maximum number of finished connections before the Dispatcher garbage collector clears
the memory reserved for those connections. The default value is 4000.
- FIN timeout
- The maximum number of seconds that connections have been finished before the Dispatcher
garbage collector clears the memory reserved for those connections. The default value
is 60.
- High Availability timeout
- The number of seconds that the executor uses
to timeout high availability heartbeats. The default value is 2.
- Wide area network port number
- A port number that is unused on all of the Dispatcher machines in a wide area network.
The Dispatcher machines use this port to exchange wide area information. The default value is 0.
- Shared bandwidth (kbytes)
- The level of bandwidth (kilobytes per second) to be shared at the cluster or executor level.
Sharing bandwidth at the cluster level allows ports to share a maximum amount of
bandwidth across several ports (applications/protocols) within the same cluster. Sharing
bandwidth at the executor level allows clusters within the entire Dispatcher
configuration to share a maximum amount of bandwidth. The default value is 0. If the value
is 0, then bandwidth cannot be shared.
Note:Specify a maximum shared bandwidth value that does not exceed
the total bandwidth (total server capacity) available.
- Maximum number of clusters
- The maximum number of clusters for load balancing. The default value is 100.
- Default maximum ports per cluster
- The default maximum number of ports per cluster. This can be overridden
on a per-cluster basis. The default value is 8.
- Default maximum servers per port
- The default maximum number of servers per port. This can be overridden on a per-cluster
or per-port basis. The default value is 32.
- Default port stale timeout (seconds)
- The default number of seconds, during which there is no activity on a connection,
before that connection is removed. The default for port 21 is 900; the default for port 23
is 32,000,000. The default for all other ports is 300. It can be overridden on a per-cluster
or per-port basis.
- Default sticky time (seconds)
- The default port sticky time for all future clusters.
Sticky time is used to create an affinity relationship between a client and a specific
server. After the sticky time has been exceeded, the client might be sent to a server
different from the previous. Default port sticky time can be overridden on a per-cluster
or per-port basis. The default value is 0, meaning that the port is not sticky.
- Default port weight bound
- The default weight bound for all future ports. This can be overridden on a per-cluster or
per-port basis. The default value is 20.
- Default port protocol
- The default port type for all future ports. This can be overridden on a per-cluster or
per-port basis. Possible values are TCP, UDP, or both protocols
TCP/UDP. The default value is TCP/UDP.
